Open Source WebSockets Servers Software

WebSockets Servers software enables persistent, two-way communication between clients and servers for real-time data exchange. These tools solve the latency issues of traditional HTTP requests by keeping a connection open for instant messaging and push notifications. This type of software serves developers who need to build live chat applications or live dashboards. Self-hosting these apps ensures that private message streams and pubsub events remain on internal infrastructure. You can manage the flow of real-time traffic without relying on external messaging brokers.

This page lists 4 open source tools in the WebSockets Servers category. The most popular are Gotify, Centrifugo and sish. Most use the MIT or Apache-2.0 license, and 4 offer an official Docker image.
